Every Friday issue of The Money Maniac closes with one quote worth keeping. This is all 38 of them, newest first, with the week each one ran and why it earned the slot.
“It never was my thinking that made the big money for me. It always was my sitting.”
An Anthropic researcher put the odds of AI wiping out humanity above 10%, the post drew 150 million views, and the Fed raised rates for the first time since July 2023 in the same week. Stocks fell for a day, then had their best session in six weeks. The issue followed the money and found no Terminator trade anywhere. Livermore, who made and lost several fortunes, said the big money came from sitting, not from reacting.
“Don't try to buy at the bottom and sell at the top. It can't be done except by liars.”
For six months the market looked straight past a war that choked the Strait of Hormuz, with the S&P 500 up 10% while Brent rose more than 50%. Then oil crossed $100 and stocks fell four days straight. Nobody rang a bell at the top. Baruch's point is that nobody ever does.
“I don't want a lot of good investments. I want a few outstanding ones.”
Ten years after leaving J.P. Morgan, the issue looked back at a first bet left alone for a decade: every $10,000 was worth about $88,000. The lesson was to pick a sector, not a stock, and stop rotating. Fisher's line is the same idea from the other direction. Concentrate on what is outstanding and leave it be.
“By 2005 or so, it will become clear that the Internet's impact on the economy has been no greater than the fax machine's.”
Nvidia grew revenue 106% in a quarter and still traded cheaper than Coca-Cola, because Wall Street expects the AI boom to fade. Krugman's 1998 call on the internet was the reminder that the smartest skeptics can be wrong about the biggest things, and that being wrong that way costs a portfolio.
“Blessed are the young, for they shall inherit the national debt.”
The national debt crossed $40 trillion on a Tuesday and barely made the news, while the 30-year Treasury yield touched 5.31%, its highest since 2007. Hoover said this in 1936, when the debt was about $34 billion. The line has aged better than the number.
“Compound interest is the eighth wonder of the world.”
Widely attributed to Einstein, but there is no record of him saying it. The line first appeared in a 1925 savings-and-loan advertisement and was not tied to Einstein in print until 1988.
Both parties were campaigning on lowering grocery prices, up 32% since the pandemic, and the issue argued neither could deliver. The one thing that outruns a rising grocery bill over decades is compounding, so the image linked to the compound interest calculator for readers to run their own number.
“Markets can remain irrational longer than you can remain solvent.”
Widely attributed to Keynes, but his biographers find no evidence he said it. The earliest print record is economist A. Gary Shilling in 1986, who probably coined the line.
SpaceX had fallen more than 50% from its peak before a single locked-up share could be sold, then closed up 6% on the day 912 million of them were freed. Anyone who shorted the lockup expiry learned Keynes's lesson the expensive way.
“The greatest enemies of the equity investor are expenses and emotions.”
Stocks had their worst day since April 2025 on Wednesday and ripped back Thursday, Microsoft posted the largest single-day gain in market history, and three Fed officials broke ranks to vote for a hike. A week like that is built to make you trade. Bogle's line names the two things trading costs.
“The function of economic forecasting is to make astrology look respectable.”
Alphabet booked the largest quarterly profit in U.S. history, $112.1 billion, while burning cash for the first time on record, because $98 billion of it was paper gains on Anthropic and SpaceX. When the headline number and the cash number say opposite things, the forecasts built on either are worth about what Galbraith said.
“If you have trouble imagining a 20% loss in the stock market, you shouldn't be in stocks.”
The big banks posted the best quarter in their history by charging the funds chasing AI, and the Buffett Indicator hit a record 234%. Stocks still had a losing week. Bogle's line is the entry test for anyone who expects the toll booth to keep paying without a drawdown along the way.
“The goal of the non-professional should not be to pick winners, but to own a cross-section of businesses.”
Wall Street's landlords were selling houses at a record pace while Berkshire bought its way into homebuilding with a $6.8 billion deal for Taylor Morrison. Two of the smartest pools of money in America, opposite bets. Buffett's advice for everyone else is not to pick a side but to own the whole board.
“The investor's chief problem, and even his worst enemy, is likely to be himself.”
Meta jumped 9% on plans to rent out its excess compute while the neocloud names got hit, and the issue argued there was more than one way to read the move. At the halfway point of a strong year, the biggest risk to a portfolio was the person holding it. Graham said it first.
“Far more money has been lost by investors trying to anticipate corrections than lost in the corrections themselves.”
The average 401(k) hit a record $167,970, but the median saver had $44,115, and the issue did the math on what that actually buys in retirement. Most of the gap is time in the market. Lynch's line is about the most common way savers cut that time short.
“The irony is that this is a market where the safest way to make money is to take some risk, and the riskiest way to make money is to be safe.”
Kevin Warsh tore up the Fed's forward guidance and went quiet on purpose, the same week a U.S.-Iran peace deal reopened the Strait of Hormuz. Less hand-holding from the Fed means more uncertainty to price. Klarman's line is the reminder that hiding from it has a cost too.
“If the job has been correctly done when a common stock is purchased, the time to sell it is almost never.”
SpaceX raised a record $75 billion, Google was selling $80 billion of stock, and a stampede of companies wanted cash at once. The issue asked whether that was a market top or the next phase of the arms race. Fisher's answer was to judge the businesses you already own, not the calendar.
“Don't look for the needle in the haystack. Just buy the haystack.”
SpaceX was days from the largest IPO in history at a $1.77 trillion valuation, and the issue asked whether public investors were about to become the exit liquidity. The same week, Vanguard's VOO became the first ETF to cross $1 trillion. Bogle's haystack was the alternative to betting on the needle.
“In the short run, the market is a voting machine but in the long run, it is a weighing machine.”
Buffett credits the line to Graham, but it does not appear in this form in Graham's own writing.
All three indexes closed at records the same month consumer sentiment hit the lowest reading in the survey's history. The issue argued the vibe gap was real but not a sell signal. Graham's machine explains how both could be true at once: votes now, weight later.
“The first rule of compounding is to never interrupt it unnecessarily.”
Greg Abel's first big Berkshire shakeup tripled the Alphabet stake and exited more than a dozen positions. The issue's read was cleanup, not panic. Munger's rule draws the distinction: prune what no longer belongs and leave the compounders alone.
“Investing is a popularity contest, and the most dangerous thing is to buy something at the peak of its popularity.”
The Dow crossed 50,000 and Nvidia added half a trillion dollars in a week, while inflation heated up, yields climbed and some Fed officials put hikes back on the table. Marks's warning was for anyone buying the most popular trade at the moment the bond market started to disagree.
“A wealth of information creates a poverty of attention.”
Stocks were at record highs with gas near $4.50, the 30-year Treasury above 5% and the AI trade broadening beyond Nvidia. With that much happening at once, the scarce resource was attention. Simon said so in 1971, before any of us had a feed.
Buffett had handed over Berkshire, Tim Cook was stepping aside at Apple, and Powell had likely held his last press conference. The issue argued that what connected them was discipline and patient decisions, not genius. Buffett's own line says why that is rarer than it sounds.
“We protect money because it's visible and throw away time because it's not.”
Cannabis stocks went vertical on a leak, then cooled when the DOJ's rescheduling order dropped with the fine print attached, a textbook buy the rumor, sell the news. Parrish's line was about the other cost of chasing a story like that: the hours it eats.
Wall Street had a new acronym, HALO (Heavy Assets, Low Obsolescence), and capital was rotating toward companies with real, hard-to-replace assets. Rotations pull people into names they cannot explain. Lynch's rule is the test before joining one.
A last-minute Iran ceasefire sent stocks, gold and Bitcoin jumping in the same week the issue walked through the tax moves worth making before April 15. Bogle's line split the two: act on the deadline, not on the rally.
“The four most dangerous words in investing are: 'This time it's different'.”
NASA had launched its first crewed lunar mission in 50 years and SpaceX had confidentially filed for what could be the largest IPO in history. The issue made the case that space was becoming a real economy. Templeton's warning was the counterweight for anyone tempted to pay any price for it.
The AI trade had moved from GPUs to memory to networking, and each wave rewarded whoever owned the choke point. The issue looked at a group of lesser-known companies suddenly at the center of the data bottleneck. Buffett's line is the check before paying up for the next one.
“Saving is the gap between your ego and your income.”
Core PCE had jumped to 3.1%, growth was slowing and an oil shock was bringing back the S-word, though Powell insisted this was not stagflation. When prices run hotter than paychecks, the savings rate is the one lever a household fully controls. Housel names what usually gets in the way.
“It's not whether you're right or wrong that's important, but how much money you make when you're right and how much you lose when you're wrong.”
Private credit was showing cracks, with a $33 billion Cliffwater fund limiting withdrawals after redemption requests hit 14% of assets in a quarter. Soros's rule is about sizing. What matters is not the batting average but how much is on the line when a trade goes wrong.
“Rule No. 1: Never lose money. Rule No. 2: Never forget Rule No. 1.”
War between Israel, the U.S. and Iran put the Strait of Hormuz, and 20% of the world's oil, in the crosshairs. The issue walked through the energy shock and which sectors win or lose. Buffett's two rules were the reminder that the first job in a shock is staying in the game.
“There are two kinds of forecasters: those who don't know, and those who don't know they don't know.”
A future-dated report from Citrini Research imagined June 2028 with unemployment above 10% and the S&P 500 down 40%, and the market sold off $600 billion on the fear of being obsolete. Galbraith's line was the antidote to treating one vivid scenario as a forecast.
“Bull markets are born on pessimism, grow on skepticism, mature on optimism, and die on euphoria.”
The 13F filings showed Berkshire dumping 77% of its Amazon stake while global stocks beat the S&P 500 by the widest margin since 1995. Templeton's four stages were the map for reading where the whales thought the cycle was.
“You make most of your money in a bear market, you just don't realize it at the time.”
The AI grim reaper was making rounds through software, insurance brokers and financial advisors, and stocks took a breather days after record highs. Davis built a fortune buying insurers nobody wanted. His reminder is that the buying you do while an industry is out of favor is where the compounding starts.
“Investing should be more like watching paint dry or watching grass grow. If you want excitement, take $800 and go to Las Vegas.”
Software stocks were down 26% for the year as agentic AI broke the per-seat business model, and the Super Bowl betting lines were flying. Samuelson's line drew the boundary between the two. The portfolio is the boring part on purpose.
“Doing well with money has a little to do with how smart you are and a lot to do with how you behave.”
Big Tech's report cards showed the AI money spigot wide open while Wall Street got pickier about how it was spent, and consumer confidence had just hit a decade low even as the hard data held up. Housel's point is that the investors who do well in that mix are the ones who behave, not the ones who out-think it.
“The big money is not in the buying and selling, but in the waiting.”
The Russell 2000 had beaten the S&P 500 for 14 straight sessions, and a week earlier 40% of readers had voted to wait for a pullback in gold that never came. Munger's line is the case for sitting through leadership changes instead of chasing every one.
“The most important organ in investing is the stomach, not the brain.”
Gold and silver were ripping on a DOJ investigation into the Fed chair, and the same issue noted that investors who did not panic-sell after Liberation Day had doubled the returns of those who did. Lynch's point is that the second group did not know more. They just held on.
“The intelligent investor is a realist who sells to optimists and buys from pessimists.”
The line is Jason Zweig's, from his note on Graham in the 2003 revised edition of The Intelligent Investor, where he summarizes Graham's core principles. Graham's own text does not contain it.
The week U.S. forces captured Maduro, the issue set aside the hot takes and asked only what was happening, what might happen next, and how markets would price it. Graham's realist is the investor who does exactly that while everyone else argues.
“The stock market is a device for transferring money from the impatient to the patient.”
A popular paraphrase of Buffett's 1991 Berkshire Hathaway shareholder letter, which calls the market a relocation center at which money is moved from the active to the patient. The impatient-to-patient wording has no primary source.
Wall Street opened the year with S&P 500 targets between 7,100 and 8,100 after three straight strong years, and the issue argued the forecasts are a compass, not a GPS. Buffett's line was the reminder that the edge is holding on through the year, not guessing where it ends.
